RE: [xsl] xalan and replace "regex"

Firstly, if you use -jar then it's irrelevant what's on your classpath. With
this option, Java ignores the classpath entirely.

Secondly, the error message indicates that someone is trying to load a class
from Saxon 6 in the course of executing an extension function. Rather than
fixing the classpath so that this class can be loaded, you need to fix the
stylesheet so that it isn't requested. As I said before, I suspect the
problem is conditional logic in the stylesheet that detects it is running
Saxon and then assumes Saxon 6.

Abel, I do not agree with you about the classpath thing. I 
have checked my classpath many times. I followed your advice 
about using saxon9.jar directly on the command line. It 
worked fine, then I changed to a different directory where I 
have some test files and did this:

[mansour(_at_)mars xslt-test]$ java net.sf.saxon.Transform 
-s:test-file.xml -xsl:sheet.xsl -o:out.xml

and it worked fine as well, so the classpath is ok, but then 
why would it work with the jar on the command line :

java -jar /opt/Programs/saxon9/saxon9.jar -s:index.xml 
-xsl:/opt/docbook/fo/docbook.xsl -o:book.fo
Warning: at xsl:stylesheet on line 8 of 
file:/opt/docbook/fo/docbook.xsl:

Warning: on line 337 of file:/opt/docbook/common/stripns.xsl:

select anything Making portrait pages on USletter paper (8.5inx11in)


This is very confusing, I don't know what is going on. Here's 
my classpath:

You can easily see at the end all the jars from saxon9 !!

     How, do I need to re-write everything to use saxon so 
I can hl 
my code or just stick to what I have?

No. You can use (most of) your XSLT 1.0 code with an XSLT 2.0 
processor. This error seems to imply that your classpath is not 
correctly configured and has nothing to do with the XSLT 
files itself. 
Try to run it from the commandline instead (java -jar 
saxon9.jar) and 
see if you still have that error.

The first line is a warning, not an error. You can ignore 
it. Or you 
can change the version attribute to 2.0 in your main 
xsl:stylesheet. 
If some of your code uses XSLT 1.0 specific features that 
have changed 
towards XSLT 2.0, you can switch on XSLT 1.0 backward compatibility 
mode by setting version or xsl:version of that specific 
instruction to 
"1.0".
